What to check on a 2008 Audi A4 before buying
The three areas where failed first tests most often had a fault, 2023–2025.
- Lamps and electrics. Ask someone to watch while you work the brake lights, indicators, sidelights, dipped and main beam, and the number-plate lamps.
- Suspension. Worth looking behind the front wheels with a torch at the coil springs, and listening for knocks over bumps on the test drive.
- Body and underside. Worth looking underneath with a torch at the sills, floor and mountings for corrosion, and at the rubber boots on the drive shafts for splits.
